  8. Alejandra Mercado • This research focuses on wireless communications with the aim of increasing transmission rates for multi-hop wireless networks, as well as reducing the cost and extending the service life of the individual network nodes. It builds on and expands the researcher’s previous work on the subject of space-time diversity in wireless communications. It extends towards cooperative diversity methods in CDMA ad-hoc networks with RAKE receivers and MIMO systems. • Our work is a novel framework of cooperative multi-input-multi-output (MIMO) diversity schemes in CDMA wireless multi-hop networks, where none of the nodes have multiple antennas. Using clusters of network nodes to relay wholly or partially correlated information to its destination both to increase effective rates and extend the nodes' service lives are concepts which are not fully developed. These proposed systems can truly achieve MIMO-type performance in a distributed way due to the use of coarse transmitter synchronization schemes complemented by RAKE receivers.

  9. Alejandra Mercado • A form of combining improved signal to noise ratio as well as security for a multi-hop wireless network is to use time-reversal techniques and antenna arrays at both transmitters and receivers. The work develops a theoretical foundation for this subject. • This work takes advantage of temporal and spatial focusing properties of time-reversal, so as to provide an independent data stream to each antenna element.
